Hi,
I just wanted to upgrade my computer from XP to Windows 7 Pro SP1 64.
Unfortunately I can not install the USB Smoothstepper driver.
I downloaded the latest.
But when I try to Install it, it says that the driver could not be installed.
I also tried Windows Testmode for unsigned drivers.
I tried several times do uninstall the device and install again.
Unplug, reboot,....
Nothing works.

Has anyone any idea?
Thanks.
